Controlling how the correlator interacts with a chain
A host plug-in controls how the correlator interacts with a chain. In the YAML configuration file, the host plug-in is the first element in the configuration of a chain. You can configure the apama.eventMap host plug-in, for example, to specify the following:
A default channel to send to.
A channel to subscribe to for events that are sent towards the transport.
A default event type for events that are sent towards the correlator (host).
